If a guy is looking for the way to Det. Kate Beckett's (Stana Katic) heart, it helps to be a cardiac surgeon. So new guy Josh Davidson (Victor Webster) already has a leg up on Richard Castle (Nathan Fillion).

Last week we told you a bit about Victor Webster, the (super hot) actor playing Beckett's new boyfriend on Castle. Now Webster is sharing more details on his character, Josh, who will be introduced on the October 11 episode "Punked." "He's this big, mysterious, hunky guy who rides a motorcycle," Webster says. "But then you'll find out he's a cardiac surgeon as well — blue collar and white collar mixed into one!"

How long will he be around? "Producers tell me they plan on having me come in and out over the next nine weeks, but they're not telling me a lot more than that," he says. Besides, he knows fans are really pulling for Castle and Beckett to get together. "At the end of the day, this show's about the sparks that fly between them, so maybe with the introduction of my character, they'll find out they really can't be without each other." Awww! Doubt it. It's never that simple.
